How many moles of H atoms are there in 47.2742 grams of C2H4Cl2?
To find the number of moles of H atoms in C2H4Cl2, we first need to calculate the molar mass of C2H4Cl2. The molar mass is 98.96 g/mol. Next, we calculate the moles of C2H4Cl2 in 47.2742 grams by dividing the mass by the molar mass which is 0.478 moles. Since there are 4 H atoms in one molecule of C2H4Cl2, multiply the moles of C2H4Cl2 by 4 to find moles of H atoms which is 1.913 moles.
Calculate the no of atom in 52 moles of helium?
To calculate the number of atoms in 52 moles of helium, you would use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply the number of moles by Avogadro's number: 52 moles × 6.022 x 10^23 atoms/mole ≈ 3.13 x 10^25 atoms. Therefore, there are approximately 3.13 x 10^25 helium atoms in 52 moles.

How many moles of PCl3 contain 3.68 1025 chlorine atoms?
To find the number of moles of PCl3, you need to first calculate the number of moles of Cl atoms in 3.68 * 10^25 atoms. There are 3 Cl atoms in each molecule of PCl3, so you divide the number of Cl atoms by 3 to get the number of moles of PCl3.
Calculate the number of moles in 5.34 10 21 atoms of boron?
To calculate the number of moles, first calculate the molar mass of boron (B), which is approximately 10.81 g/mol. Then use the Avogadro's number (6.022 x 10^23) to convert the number of atoms to moles. So, moles = number of atoms / Avogadro's number = 5.34 x 10^21 / 6.022 x 10^23 ≈ 0.089 moles of boron.
How many atoms are their in 0.39 moles of Ga?
To find the number of atoms in 0.39 moles of Ga (gallium), you first need to calculate the number of moles in 0.39 moles of Ga. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms. So, for Ga, there would be approximately 2.35 x 10^23 atoms in 0.39 moles of Ga.

To determine the number of moles, first calculate the number of moles in one mole of uranium using Avogadro's number (6.022 x 10^23 atoms/mol). Then, divide the given number of atoms by the number of atoms per mole to find that 4.70 x 10^26 atoms of uranium represents 7.81 moles.
How many atoms are in 3 moles of potassium nitrate?
To calculate the number of atoms in 3 moles of potassium nitrate (KNO3), you use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the molar mass of KNO3 (101.1 g/mol) then multiply that by 3 to get the total mass in grams. Next, divide the total mass by the molar mass to get the number of moles, and finally multiply the number of moles by Avogadro's number to get the number of atoms. For 3 moles of KNO3, there are approximately 5.4 x 10^24 atoms.
